To all whom it may concern:

Be it known that I, CHARLES C. SPENGLER, a citizen of the United States,residing at Rockford, in the county of l/Vinnebago and State ofIllinois, have invented certain new and useful Improvements inChange-Makers, of which the following is a speciiication.

This invention relates to change-makers, and refers particularly toimprovements in the basis-changing mechanism of such changemakersvthatis to say, the mechanism that adapts the machine to give change from anyone of the several dierent bases within its scope. In the presentembodiment these bases are one dollar, fifty cents, twenty-five cents,and ten cents.

In the accompanying drawings, Figure 1 is a longitudinal verticalsectional view on dotted line l l, Fig. 2, taken through a changemaker,showing the improved basis-changing mechanism of my invention in itsapplication to said change-maker. Fig. 2 is a transverse verticalsectional view through said changemaker, taken on dotted line 2 2, Fig.l. Fig. 3 is a detail top plan view taken on broken dotted line 3 3,Fig. 1. Fig. 4 is a top plan view of said basis-changing mechanism. Fig.5 is a sectionalview on dotted line 5 5, Fig'. l, taken through thechange-maker, showing in side elevation the basis-changing mechanism.Fig. 6 is a view similar to the preceding one of the basis-changing keysdepressed. Fig. 7 is a transverse sectional view taken on dotted line 77, Fig. 6. view of the change-maker, showing the operating-levers forthe basis-changing mechanism.

In the drawings a change-maker of common'construction is shown, of whichchangemaker A refers to the framework, A to the operating-keys, A2 tothe rock-shafts for supporting said keys, A5 to the arms extendingdownwardly from said rock-shafts, and A, A5, A5, A5, and A8 tocoin-slides for dimes, dimes, nickels, quarter-dollars, andhalf-dollars, which coins are adapted to lie in the coinreceptacles A5,A15, A11, A12, and A15, respectively. The coin-slides are suitablymounted to have an endwisemovement in the framework and so that one endof said slides re- Fig. 8 is a detail face ciprocates beneath saidcoin-receptacles. A releasing-slide A11 for the basis-changing mechanismis also provided, which releasingslide has a releasing-stud A15 near oneend of said slide. As in other change-makers of a similar kind, pressureexerted upon one of the operating-keys A oscillates the rock-shaft whichsupports said key and produces avreciprocation of one or more of thecoin-slides. All of the coin-slides and their actuating-keys arerestored to a normal position by means of the restoring rock-shaft A15,having pins A17 extending downwardly from said rock-shaft into suitableopenings in all of the coin-slides A1, A5, A5, A7, and A5, and thereleasing-slide A11, which restoring rock-shaft ispheld in a normalposition by the coil-spring A15, secured at one of its ends to an armA15 on said shaft and at its other end to a stationary point on thesupporting-frame A. In the mechanism herein shown the coin-slides do notengage the coins within the receptacles A5, A15, A11, A12, and A13unless the forward ends of said slides are raised slightly, and thisraising movement is accomplished by means of the basis-changingmechanism of this invention, which mechanism and the manner of operatingit will next be described.

The basis-changing mechanism is mounted principally upon an angle-bar B,fixed in any suitable manner in the framework A. On one side of theangle-bar five two-arm anglelevers B', B2, B5, Bi and B5 are pivotallymounted, the lower arm of each of which levers extends transverselybeneath said anglebar. The upper arms of said angle-levers projectoutwardly to underlie pins B5, B7, B5, B5, and B15, slidabl y mounted insuitable openings Within the supporting-frame A and beneath thecoin-slides A1, A5, A5, A7, and A5. The pawl B11, pivotally mounted uponthe angle-bar B, has a laterally-extending operatingwedge B12, adaptedto be engaged by the releasing-stud A15, and is held upwardly inengagement with its work by a flat spring B15.

Four basis-changing slide-bars C, D, E, and F are slidably mountedwithin the anglebar B upon suitable guide-studs, each of said slide-barsbeing provided with integral projections adapted to engage the lowertrans- IOO verse arms of certain of the levers B, B2, B3, B1, and B5.The slide-bar C, being the one that controls the dollar basis, hasprojections C', C3, C3, C1, and C5 for all of said angle-levers,respectively. The bar I), controlling the fifty-cent basis, hasprojections D, D3, D3, and D1 for the angle-levers B, B2, B3, and B1,respectively. The sliding bar E for the twenty-live cent basis hasprojections E, E2, and E3 for the angle-levers B, B2, and B3,respectively, and the bar F for the ten-cent basis has one projectiononly-to wit, the projection F3 for engaging the angle-lever B3. Each ofthe bars C, D, E, and E has an inclined tooth C, D, E3, and F11,respectively, for engaging with the pawl B11, whereby any one of saidbars is held in a rearward position against the action of its respectivecoilsprings C1, D1, E7, and F1. To move said bars C, D, E, and Erearwardly, four bellcranks C3, D3, E3, and E3 are provided, saidbell-cranks being pivotally mounted on the angle-bar B, each having anarm to impinge against the forward end of each one of said bars, alsoanother arm forwardly extending to underlie one of the fouroperating-levers C9, D", E, and F, pivotally mounted on the front faceof the supporting-framework A and provided with indicating-keys C10,D10, E1, and F13.

As hereinbefore indicated, this basis-changing mechanism has fourstandards or bases* to wit, a one-dollar, a fifty-cent, atwentylive-cent, and a ten-cent basis. To set the mechanism for anybasis of the four mentioned, one of the basis-changing keys C10, D1",E10, and F10 is depressed. For the sake of illustration let it beassumed that the dollar key C10 be depressed. The downward movement ofthe lever C11 oscillates the bellcrank C3 upon its pivot, moving thebasischanging bar C rearward against the action of its spring C7 untilits tooth C is thrown rearward of the point of the pawl B11. As soon asthis occurs said pawl is thrown upward by the flat spring B13, holdingsaid bar in its rearward position. This rearward movement of the bar Cbrought the projections C1, C3, C", G1, and C5 of said bar into contactwith the lower arm of each of the angle-levers B', B3, B3, Bi, and B5,imparting to said levers an oscillatorymovement. Thisoscillatorymovementof the levers B1, B3, B3, B1, and B5 raises the pins B3, B1, B3, B3, andB13, which in turn raises the ends of the coin-slides A'i, A5, A, A7,and A3. The mechanism is now placed in position to give change from onedollarto wit, upon purchases wherein a dollar is given in payment forpurchases of a smaller amount. The coin-slides A1, A3, A, A1, and A3, orcertain ones of said slides, are moved forward by depressing' theoperating-keys A of the change-maker. The releasing-slide A11 isconnected to move forward by the depression of any one of theoperating-keys A', and

when the releasing-stud A15 upon said releasing-slide is brought intocontact with the operating-wedge B12 of the pawl B11 said pawl is rockeddownward upon its pivot against the action of its spring B13,withdrawing the point of said pawl from engagement with the tooth C ofthe bar C. When thus released, the bar C is thrown forward into itsnormal position by its coil-spring C1, and this forward movement of thebar AC also restores the other parts of the basis-changing mechanism totheir normal positions. When the fifty-cent key D10 is depressed, onlythe levers B, B2, B3, and B1 are oscillated, and consequently only thepins B, B7, B3, and Blq and the coin-slides A", A3, A11, and A7 areraised. The basis-changing mechanism is held in position upon thefiftycent basis by the pawl B11 engaging the tooth D3'. It is releasedby the forward movement of the releasing-slide A11 and stud A13,withdrawing said pawl from said tooth, as hereinbefore described. Whenthe mechanism is set for a certain basis, it may be changed to anotherbasis by simply depressing the key of the desired basis, for in passingthe point of the pawl B11 the engaging tooth of the bar of the desiredbasis depresses said pawl suinciently to release the tooth of the barpreviously held, releasing said bar to the action of its coil-spring,which latter returns it to a normal position.

It is clear that many changes in and modifications of the mechanismherein shown and described may be resorted to without departing from thespirit and scope of my invention, wherefore I desire to have itunderstood that I do not limit myself to the particular embodimentthereof herein set forth.
